[gduns - with the Lord]

I also run karaoke in stereo...... much better sound.

As far as retaining the left mplx settings. Mark the song (in the manual how to). edit the songs later, and it will save these setings for that particular track. you can also select it when importing, and it will also remember. when you do the edit it changes it in the songs database as well as in the file header it writes. so you wont loose this setting when you do a database rebuild.
